Researchers took a whiff of Egyptian mummies for science — they ‘were surprised by the pleasantness of them'
LONDON — At first whiff, it sounds repulsive: sniff the essence of an ancient corpse.
But researchers who indulged their curiosity in the name of science found that well-preserved Egyptian mummies actually smell pretty good.
'In films and books, terrible things happen to those who smell mummified bodies,' said Cecilia Bembibre, director of research at University College London's Institute for Sustainable Heritage. 'We were surprised at the pleasantness of them.'
'Woody,' 'spicy' and 'sweet' were the leading descriptions from what sounded more like a wine tasting than a mummy sniffing exercise. Floral notes were also detected, which could be from pine and juniper resins used in embalming.
The study published Thursday in the Journal of the American Chemical Society used both chemical analysis and a panel of human sniffers to evaluate the odors from nine mummies as old as 5,000 years that had been either in storage or on display at the Egyptian Museum in Cairo.
The researchers wanted to systematically study the smell of mummies because it has long been a subject of fascination for the public and researchers alike, said Bembibre, one of the report's authors.
Archeologists, historians, conservators and even fiction writers have devoted pages of their work to the subject — for good reason.
Scent was an important consideration in the mummification process that used oils, waxes and balms to preserve the body and its spirit for the afterlife.
The practice was largely reserved for pharaohs and nobility and pleasant smells were associated with purity and deities while bad odors were signs of corruption and decay.
Without sampling the mummies themselves, which would be invasive, researchers from UCL and the University of Ljubljana in Slovenia were able to measure whether aromas were coming from the archaeological item, pesticides or other products used to conserve the remains, or from deterioration due to mold, bacteria or microorganisms.
'We were quite worried that we might find notes or hints of decaying bodies, which wasn't the case,' said Matija Strlič, a chemistry professor at the University of Ljubljana. 'We were specifically worried that there might be indications of microbial degradation, but that was not the case, which means that the environment in this museum, is actually quite good in terms of preservation.'
Using technical instruments to measure and quantify air molecules emitted from sarcophagi to determine the state of preservation without touching the mummies was like the Holy Grail, Strlič said.
'It tells us potentially what social class a mummy was from and and therefore reveals a lot of information about the mummified body that is relevant not just to conservators, but to curators and archeologists as well,' he said. 'We believe that this approach is potentially of huge interest to other types of museum collections.'
Barbara Huber, a postdoctoral researcher at Max Planck Institute of Geoanthropology in Germany who was not involved in the study, said the findings provide crucial data on compounds that could preserve or degrade mummified remains.
The information could be used to better protect the ancient bodies for future generations.
'However, the research also underscores a key challenge: the smells detected today are not necessarily those from the time of mummification,' Huber said. 'Over thousands of years, evaporation, oxidation, and even storage conditions have significantly altered the original scent profile.'
Huber authored a study two years ago that analyzed residue from a jar that had contained mummified organs of a noblewoman to identify embalming ingredients, their origins and what they revealed about trade routes.
She then worked with a perfumer to create an interpretation of the embalming scent, known as 'Scent of Eternity,' for an exhibition at the Moesgaard Museum in Denmark.
Researchers of the current study hope to do something similar, using their findings to develop 'smellscapes' to artificially recreate the scents they detected and enhance the experience for future museumgoers.
'Museums have been called white cubes, where you are prompted to read, to see, to approach everything from a distance with your eyes,' Bembibre said. 'Observing the mummified bodies through a glass case reduces the experience because we don't get to smell them. We don't get to know about the mummification process in an experiential way, which is one of the ways that we understand and engage with the world.'

Authorities expose secret pipeline fueling endangered species trade: 'An important threat to the biodiversity ... and the wider region'
Protecting animal species from exploitation and extinction requires accurate information about the animals and how humans are interacting with them. Sometimes, that information is hard to get, as is the case for North Korea due to its lack of open communication with the rest of the world. However, a recent study published in the journal Biological Conservation sheds light on North Korea's wildlife — and, unfortunately, the situation is dire, University College London reported. The information in the report came from interviews with North Korean defectors directly involved in the illegal wildlife trade, including hunters, buyers, and middlemen, gathered between 2021 and 2022. This group revealed that despite North Korea's system of protected habitats and protected species, it is extremely common for endangered animals to be hunted for meat, skins, traditional medicine ingredients, and other resources. Some of the animals and parts are traded within North Korea, with the rest crossing the border to China. The North Korean government itself is involved in illegal wildlife trade, which violates both its own laws and international law regarding the treatment of endangered species. Lead author Dr Joshua Elves-Powell said in the UCL report: "The widespread harvesting of North Korea's wildlife, driven by the economic limitations of the North Korean state and the shortages of food, medicine, and basic goods experienced by many of its citizens, is an important threat to the biodiversity of North Korea and the wider region." Protected animals like Amur tigers, Amur leopards, Asiatic black bears, long-tailed gorals, and Eurasian otters are among the species of most concern in this report. But after an economic collapse and famine in the 1990s, it's likely that almost every mammal species heavier than half a kilogram (just over a pound) has been affected to some extent, UCL reported. As this data makes clear, many people in North Korea are relying on the animals in the country for food or their livelihoods. Unfortunately, wildlife is not an unlimited resource. The more those animal populations are pushed toward extinction, the more the people involved will suffer. Species that are lost can never be recovered, and populations that are damaged may take many years of conservation efforts to restore. It doesn't just impact the animals within North Korea's borders. Normally, animals should be able to cross the border freely, interbreeding and searching for food. Populations near the border will be impacted by the activities that happen on only one side, as there will be fewer individuals to maintain genetically diverse populations. The study authors called on China to crack down on buyers and put economic pressure on North Korea to stop the illegal wildlife trade. As the market for the majority of illegal animal parts that leave North Korea, China has the power to shut down demand. Do you think people should be allowed to keep exotic animals as pets?

First bacteria we ever meet can keep us out of hospital
The first bacteria our bodies meet – in the hours after we're born – could protect us from dangerous infections, UK scientists say. They have shown, for the first time, that good bacteria seem to halve the risk of young children being admitted to hospital with lung infections. The researchers said it was a "phenomenal" finding and could lead to therapies that boost good bacteria in babies. Our early encounters with microbes are thought to be crucial in how our immune system develops. We come out of the womb sterile, but this doesn't last for long. All the nooks and crannies of the human body become home to a world of microbial life, known as the microbiome. More than half your body is not human Microbiome podcast: The Second Genome Researchers at University College London and the Sanger Institute investigated the earliest stages in our body's colonisation by bacteria, fungi and more. They collected stool samples from 1,082 newborns in the first week of life. The team then performed a massive genetic analysis on all the DNA in the samples to work out exactly which species were present and how common they were in each child. They then tracked what happened to those babies, using hospital data, for the next two years. One particular early inhabitant of the human body, Bifidobacterium longum, seemed to have a protective effect. Only 4% of babies with this species would spend a night in hospital with a lung infection over the next two years. Babies with different starter-bacteria were two-to-three times more likely to need to stay in hospital. It is the first data to show the formation of the microbiome affects the risk of infection. "I think it's really phenomenal. It's amazing to be able to show this. I'm excited," Prof Nigel Field, from UCL, told the BBC. The most likely culprit for children ending up in hospital is respiratory syncytial virus (RSV), but what joins the dots between this and B. longum? That is the "million dollar question" for Prof Field. We know B. longum starts off digesting breast milk which both contains food for the baby and encourages good bacteria. The exact details have not yet been worked out, but either the bacteria themselves or the compounds they make by digesting food are interacting with the immune system "and are influencing the way in which the immune system matures and is able to recognise friend from foe," according to Prof Field. The protective bacteria were found only in babies that came into the world via a vaginal delivery rather than a caesarean. Even then they were not discovered after every vaginal delivery. The researchers say their findings do not justify the practice of vaginal seeding, where some new parents smear babies with a swab taken from the vagina. How method of birth alters babies' bacteria The good bacteria seem to be coming from the end of the mother's digestive system, an idea known in the field as the "first lick". "I feel pretty confident in saying that vaginal seeding is not a good thing," said Prof Field. However, the long-term ambition is to come up with microbial therapies – like a probiotic yogurt – that could be given to babies to set their microbiomes on a healthy path. Prof Louise Kenny, from the University of Liverpool and a consultant obstetrician and gynaecologist, said: "A caesarean section is often a life-saving procedure, and can be the right choice for a woman and her baby." She said that while the benefit was seen only in babies born vaginally, it was not in every child born that way so "further research is needed to create a full, nuanced picture".
